More specifically it relates to a straw chute for the thresherpart thereof. v v

Certain types of traveling combinescomprise a thresher body with a,straw discharge: opening atone end, a header orharvester at one; side otthe thresher and aground. wheel somewhat-beyond the other side of thethresher body. The width of cut by the harvester is such'that" ononetrip across the field beingv cut the: outside wheel follows a linefollowed by thethresher body on the previous trip and consequently mustrun through straw discharged bythe thresherbody on the previous trip.Accordingly, itisdesirable to have the straw discharged to one side ofthe centerline of the thresher body so that the outside wheel will notrun through the straw.

An object of the present invention is to provide an improved thresherconstruction.

Another object is the provision of means for guiding straw discharged atthe rear of a thresher body to one side of the centerline of thethresher body.

A further object is to provide a chute adapted to be connected to astraw-discharge hood at the rear of a thresher body.

Another object is the connection of a chute to a straw-discharge hood atthe rear of a thresher body.

Another object is to provide a chute including a stifiening member whichis employed in the connection of the chute to the straw-discharge hoodof a thresher body.

According to the present invention, a chute is connected to a downwardlyopening straw-discharge hood at the rear of a thresher body. The chutecomprises a vertical wall extending from the end of the thresher bodyand a downwardly and transversely extending wall from the side of thethresher body which receives straw from the hood and discharges it atone side of the centerline of the thresher body.

In the drawings Figure 1 is a view in perspective showing the novelchute of the present invention secured at the rear of a thresher body;

Figure 2 is a side view of the chute joined to the end of a thresherbody with part of the thresher body being cut away;

Figure 3 is an end view of the same; and,

Figure 4 is a detail showing of a portion of the connection between thechute and the thresher body.

The reference numeral I0 designates a thresher body, only the rearportion of which is shown.

yond them is a downwardly openingstrawdischar-ge hood- IL; The-thresherbody is open inw-ardlyofand-belowthe hood I2 a at I;3-, and'a chafierextension I4protrudes; whichis moved fore and aft so as to feed thestraw out the-end ofthethresher body In. J j I s A chute I5 is securedto the hood I2, which chute comprises a generally vertical wall: I6extending from and somewhat beyond the end wall of the hood I2 attheend' ofthe thresher body and a wall-= I1 extending downwardly andvtransversely of: the thresher body fromthe side of the hood at the sideof the thresher body. The wall I -'I- joins the wall IB- atone side and:has an: upturned edge I8 at the other side. The wall I6 is connected tothe end of the hood by means of short tubular sections I9 securedalternately to wall I6 and the hood I2 and a pin 29 passing through thetubular sections I9. A cover 2! extends from beneath the wall I'I, beingjoined thereto by means of an angle or stiffener member 22 which extendsup the side of the hood I2 and is connected at the top'thereof by meansof a bolt 23 and a member 24 on top of the hood I2. The cover 2I whichencloses the chaffer I4, comprises a vertical triangular-shaped wall 25and a vertical wall 26 extending as a continuation of the side of thethresher body I0, serving to close off the open part inwardly of andbeneath the hood which is below the wall II. The cover 2| and anglemember 22 are connected to the side of the thresher body III by means ofa tubular section 21 secured to the wall 26, tubular sections 28 securedto the side of the thresher body, tubular sections 29 secured to theangle member 22, and a pin 30 passing through the tubular sections andan opening 3! in the angle member 22.

In operation, the thresher body functions in the usual manner Which forthe purposes of the present invention need not be described. A blast ofair from a fan within the thresher causes straw to be discharged fromthe hood I2, and from the chaffer I4. The straw falls from the strawwalkers II into the chute I5 and the fore and aft movement of thechaffer extension I4 moves the straw rearwardly onto the chute I5 and isdischarged onto the ground with the aid of the wall I! to one side ofthe centerline of the thresher body and generally in a windrow. Withoutthe chute I5, the straw would be discharged along the centerline of thethresher body and on both sides thereof. Thus the ground wheel beyondthe side of the thresher, by passing along the line followed by thecenterline of the thresher body on a previous trip across the field,would run through straw discharged on the previous trip. By the presentinvention the ground wheel does not run through straw since the strawhas been discharged to one side of the centerline of the thresher body.

The chute embodying the present invention may be quickly and easilyremoved from the thresher body. For removal, the angle member 22 isdisconnected from the member 24 by re-. moval of the bolt 23, and pins20 and 30 are removed, respectively, from tubular sections [9 andtubular sections 21, 28 and 29. The chute l5, cover 2|, and angle iron22 come offas a unit.

As previously stated, the purpose of the cap 2| is to cover the openpart beneath and inwardly of the hood [2 which is beneath the inclinedwall I! of the chute l5. air which effects the discharge of straw to thehood I2 cannot cause straw to be discharged in wardly of the wall 11 andalong the width of the thresher body rather than in a windrow and to oneside of the centerline. The angle iron 22 serves to stiffen the chuteand to prevent its being bent out of shapeduring use and when removedfrom the hood.

It is the intention to limit the invention only within the terms of theappended claims.

What is claimed is:

l. The combination with a thresher body having a downwardly openingstraw-discharge hood at one end and being open inwardly of and below thehood, of a device having a first generally vertical wall extending fromthe side of the hood at the rear of the thresher body, a second wall ex-I end of the thresher body and comprising short Consequently, the blastof l tending from a side of the hood at the side of the thresher bodydownwardly and transversely of the thresher body for discharging strawin a windrow at one side of the centerline of the thresher body, aportion extending from beneath the second wall and forming a closure forthe part of the opening in the thresher body inwardly of and below thehood, said part being beneath the second wall, means connecting thefirst wall of the device and the side of the hood at the tubularsections alternately connected to the hood and the wall and a pinpassing through the tubular sections, means connecting the side of thehood at the side of the thresher body and the said portion of the deviceand comprising a tubular portion in the hood and the device and a pinpassing through the sections, and an angle member connecting andextending along the juncture of the second wall and the said portion andalso extending up the side of the thresher and being secured at the topthereof.

2. The combination with the straw dischargehood of a thresher, of astraw-deflecting chute having a vertical wall, an inclined wall, and astiffener bar extending along an edge of the inclined wall and the sideof the straw-discharge hood and being secured at the top thereof, andmeans securing the chute to the hood comprising tubular sections securedto the hood and vertical wall, a first pin passing through the sections,and a second pin passing through a tubular section secured to the hoodand a hole in the stiffener member.
